You spin me round! Driving wheels machined for brand new B17 class locomotive.

There are 2 brand new steam engines being built in Sheffield at CTL Seal. Here's a closer look at the B17 which is now having its six driving wheels machined. With a smokebox outer wrapper now sitting on the frames too, it is really starting to look like an engine!

It gives me a lot of pleasure to see us creating some beautiful precision engineering in Britain these days. Something we have lost so much of.

[@ceanothus_bluemoon]

So exciting to see these new engines coming along so well, and bearing the name of Sheffield on the front too. Please keep bringing us updates!

[@johndrew3202]

Very interesting to see how they are progressing since they went to CTL Seal. Hope both projects manage to progress in good time to completion. Thanks for your update Tom.

[@patmancrowley8509]

This project gives me the FIZZ! (bubbly with happiness)

[@stevesalvage1089]

Great to see the experience and expert work in recreating something from the past to the future, well done and thanks for sharing Tom ,

[@tomingall74]

Thanks for watching. Both Hengist and the B17 now really pushing forward.

[@cedarcam]

Great to see the wheels will soon be ready. At the open day they were saying one was in the machine and hoped the rest would follow without a break in the work. Looks like that went to plan

[@johnpearson8657]

Yes, there were 5 stacked up on display and the first was on the machine. The one in the video was the third, so three more to go. Or it might be two by now!

@@johnpearson8657 Thanks for the update.

Nice!

[@alanorion1]

Good Progress Well Done !!!

[@emagenevanhorn1543]

When’s our next update

[@rearspeaker6364]

and us yanks have a hard time building one new engine, and here they are building two!

[@scootergrant8683]

Oh it's more than that. We've just finished another one this year. Named Beachy Head.

[@rearspeaker6364]

@@scootergrant8683 soon, the English will have more operating steamers then the U.S.

[@maly2ts408]

Will it be on roller bearings

[@johnpearson8657]

Yes. The Trust already has all 10 of the Timken Tapered Roller bearings in stock - the 6 for the Drivers and 4 for the Bogie. To house these, we already have the Driving Wheel Coupled Axleboxes and Cannonboxes - one of which was, fully machined, on display at the Open Day. The Bogie has been redesigned to take these bearings and its own Cannonboxes, which is why manufacturing and casting will start when the redesign is approved by the regulator - we have the patterns for both the bogie wheels and the cannonboxes.

Why waste money on paste and a good finish on bare frames? Remember the Patriot issue of bolting up over scale, you've pasted the cylinder faces?

[@johnpearson8657]

Protecting the frames from any corrosion with a good primer and undercoat on a prepared surface whilst it is easily accessible was considered the right thing to do by the Trust at this time. Fairly soon, some sections will be more difficult to get to once the rear two Driving Wheelsets are in place and the manufacture and fitting of cylinders is not imminent as the focus is on the Bogie and Smokebox design and manufacture. When we are ready to fit any items such as the cylinders, the appropriate area will be carefully cleaned back to metal, something that didn't happen in the example quoted. The Trust is building this loco to run from day 1 on the mainline, and as such has, and will continue to have, the complete paper trail of approvals for each stage (design, manufacture and fitting) and works closely with the appropriate Railway Regulator and this would certainly include items like the fitting of the cylinders.
